Abstract: PURPOSE:To eliminate a nondetection state and to enable stable detection by constituting a detection part by combining a magnet which is suspended from a base body by a suspension cord with a magnetoelectric converting element which outputs a detection signal corresponding to the intensity of a magnetic field. CONSTITUTION:The detection part 1 provided in the inclination sensor is consti tuted by connecting the suspension cord 12 to a magnet holder 13 where the magnet 14 is held. This suspension cord 12 is connected to a support rod 16 fixed to the base body 11 vertically and the magnet 14 is suspended. The magne toelectric converting element 15 is fixed on the side of the base body 11. The distance between the magnet 14 and element 15 is less when the base body 11 slants to the right than the case of the base body 1 does not slant, so the intensity of a magnetic field that the element 15 receives increases. When the base body 11 slants to the left, the distance between the magnet 14 and element 15 increases, so the intensity of the magnetic field that the element 15 receives decreases. Therefore, the inclination can be detected with the detection signal outputted by the element 15 and whatever method is used to slant the base body 11, the inclination can be detected immediately.

Abstract: PURPOSE: To obtain the differential image of an original picture easily by a simple unit by image-forming two light rays, differing in light-path length by a fixed value, on a recording medium and by causing a differential interference.  
     CONSTITUTION: Original 0 with a drawn original picture is lightened by lamp 1 and part of its reflected light is image-formed on incoherent/coherent converting element 4 after being reflected by half mirror 3. As a result, an exposed part of element 4 becomes transparent and the original picture is memorized. A ray emitted from laser light source 5 is amplitude-modulated by the picture stored in element 4 and image- formed on the surface of parallel reflecting layer 9, and the ray is reflected by the top and reverse surfaces of layer 9 and image-formed on recording medium 11. Rays reflected by top and reverse surfaces of layer 9 respectively shift mutually by a slight distance and adjusting the difference in light path to λ/2 obtains a phase difference of (π); and consequently two rays image-formed on medium 11 cause a differential interference to obtain a differential image.

Title: Infrared ray detector
Inventor: NAGAHAMA KOUKI
IPC: H01L35/00
Filed: 1983-09-06
Abstract: PURPOSE:To contrive the improvement of the performance of infrared ray detection by utilization of the fact that a tunnel current flowing through the p-n junction varies with infrared rays. CONSTITUTION:When the energy in the lower end of the conduction band (a) of an n type semiconductor Dn becomes smaller than in the upper end of the valence band (b) of a p type semiconductor Dp, the tunnel current (g) flows through the p-n junction (j). Since the tunnel probability of electrons (e) or holes (h) varies with the interposition of photons, a detector for infrared rays (d) can be manufactured by utilization of this phenomenon. The proper selection of the forbidden band width of a used semiconductor material, the impurity concentrations in the p type and n type semiconductor regions Dp and Dn, and the bias voltage impressed on the p-n junction (j) enables the formation of an infrared ray detector sensitive to a desired wavelength band. A material having a larger forbidden band width than that of the energy corresponding to a detected wavelength can be used, and the infrared ray detector of the band of a wavelength of 10mum can be used by the use of Si, Ge, GaAs, etc.

Abstract: PURPOSE:To form an element with reduced defects in its crystal structure, by distributing an impurity to form a stripe over a predetermined range on the junction depth of the element by subjecting the element to a plurality of ion implantations or to an ion implantation with the implanting energy changed continuously. CONSTITUTION:After a mask 19 is formed on an epitaxial layer 16, the first ion implantation is carried out to form a gauge G'i. The second ion implantation is then carried out to form a gauge G''i. For the second ion implantation, an energy E2 larger than that for the first implantation is selected so as to increase the depth xj of the junction. Further, the third ion implantation is performed to form a gauge G'''i with an energy E3 larger than that for the second implantation so as to further increase the depth xj of the junction. A required number of ion implantation processes are thus repeated before annealing. During the annealing process, any damage in the crystal structure can be repaired approximately completely. Thus, a gauge having stable characteristics can be obtained.
